JAR CLOSURE.

part of the user, and to provide means which may be re-used indefinitely.

These objects, and other advantag ous ends which will be described hereinafter, l attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a side elevation partly fragnientary showing the top of a jar provided with one form of my invention,

Figure 2 is a view substantially at right angles to that of Figure 1;

Figure 3 a top plan view of Figure 2, and

Figure f a section on 4-& of Figure 1.

In the embodiment of my invention I provide a jar 2 of the usual form except that it is equipped with oppositely disposed bosses 3 and 4 provided with vertical channels 5 perferably undercut at 6. I also provide a yoke 7, preferably of resilient metal, the arms of which terminate in cross pieces 8 so that, when in use, each end of the yoke is in the form of an inverted T. Each of cross pieces 8 may be provided, at one enc, with an angular lip 9. Midway of its length the yoke is bored to receive a screw 10 provided with a wing head 11. I provide a cap 12 having in its upper surface a central depression 13 adapted to receive the end of screw 10. The under part of the cap is provided with a downwardly extending annular tenon 14, preferably rectangular in cross section, and the top of the jar is provided with an anular channel 15 adapted to receive the tenon on the cap. The channel is slightly larger in cross section than the tenon depending from the cap in order that it may receive a compressible gasket 16.

The attachment is simple, and inexpensive and the seal highly efiective. It may be applied or removed almost instantan-- While I have described by invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what 1 claim as new and desire to secure by Letters Patent is 1. In combination with a jar having an annular mortise in its upper surface and provided near its top with peripheral lugs having oppositely disposed vertical channels, and a cap having an annular depending tenon adapted to extend into the mortise in the jar, of a yoke having arms adapted to extend into the vertical channels, the arms having T-shaped ends adapted to extend under the lugs, andthe arch of the yoke having a central bore, and a thumb screw ex tending through the bore and adapted to engage the cap.

2. In combination with a jar having an annular mortise in its upper surface and provided near its top with undercut peripheral lugs having oppositely disposed vertical channels, and a cap having an annular depending tenon adapted to extend into the mortise in the jar, of a yoke having arms adapted to extend into the vertical channels,

the arms having T-shaped ends adapted to extend under the lugs, and the arch of the yoke having a central bore, and a thumb screw extending through the bore and adapted to engage the cap.

In testimony whereof I aflix my signature.
